IBLEACHIN G, DYEING, OR OTHER FLUID TREATMENT OF YARNS WOUND IN THE FORMOF CHEESES.

Application filed December 22, 1923. Serial- No. 682,803.

To all whom it may concern:

Be it known that we, JOHN BRANDWOOD, THOMAS BRANDWOOD, and JOSEPH BRAND-WOOD, all subjects of the King of Great Britain and Ireland, andresidents of Elton, Bury, in the county ofLancaster, England, haveinvented certain Improvements in and Relating to the Bleaching, Dyeing,or Other Fluid Treatment of Yarns Wound in the Form of Cheeses, of whichthe following is a specification.

This invention relates to means for compressing yarn vpackages whichhave been placed upon perforated or analogous spindles for the purposeof dyeing or other treatment of the yarn packages, as described forinstance in the specification to United States Letters Patent No.1454312 granted' to two of the present applicants. .It is a necessity,as pointed out in the said prior specification, that when the-yarn inthe form of cheeses is to be dyed in bulk, the yarn of all the cheesesshould be of equal density, to prevent uneven penetration of the dyeingliquor or analogous fluid. The gravity plate and screw meansdescribed-in such prior specification, whereby all the cheeses on aplurality of spindles are compressed by the weight of a top or gravityplate which is further pressed down by a nut engaging on a threadedcentral spindle, requires careful handling and attention to ensure thatthe pressure shall be equal on the yarn contained.

on each spindle, and means for compressing the yarn mass on each spindlesingly, whilst ensuring that the pressure of the yarn mass of onespindle shall be equal to the pressure on the yarn mass of another, is adesiderafor each perforated or analogous spindle a '45 turn. It isthe-object of this present invention to provide such means of evencompression.

In carrying the invention into effect in an apparatus as abovereferredto we provide separate top plate adapted to slide upon thespindle, with means for pressing each top plate separately upon the yarnmass upon the spindle, and means upon the spindle itself for securingthe top plate in fixed relation thereto when the compression has reacheda given point. Thus with a yarn bulk of equal-compressibility on thewhole a of the spindlesft securing means as between the spindleand' topplate after the fitted upon a spindle with means for pressmg 1t downupon the mass of yarn cheeses fitted upon the-spindle;

Figure 2 is a side elevation of a top plate upon a spindle, the pressuremeans being removed, and the securing means applied to the top plate;

Figure 3 is a view similar to Figure 1 but at right angles thereto; and

Figure 4 is a fragmentary view in side elevation showing two spindles.with top plates, the yarn being compressed on each spindle and ready fortreatment.

Referring to Figure 1, 5 is acentral rod or spindle which correspondstothe central rod or spindle of the drawings to specification No. 1454312referred to above. This rod 5 is threaded at 6 to receive a tappedcylindrical member 7 in which are fitted pins 8 one at each end of adiameter of the cylindrical members. 9 is a lever of any convenientlength the end 10 of which is bifurcated, each limb of the bifurcationbeing slotted as at 11 the width of the slot ll'being suflicient toallow of each limb of the bi urcated end 10 being slipped over a pin 812 is a bell shaped pressure member which may be cast and has formedthereon the lugs 13 14.is a top plate annular in form and the diameterof which is equivalent to the diameter of the cheeses 15 fitted upon aperforated spindle 16 when the said cheeses have been fully compressed.The

top plate 14 is provided with tubular boss or extension 17 of a diameterequal to the external diameter of the pressure member 12 at the base ofthe latter, or of any less diameter. The top plate 14 andits extension17 have an easy sliding fit on spindle 16.

' At the .desired distance below the upper extremity of each spindle 16is formed an orifice 18 (Fi ure 3) which extends through the wall of thesaid spindle, and the lower portion of the bell shaped member '12 is cutoutas at 19 Figures 1 and The lever 9 has orifices formed in it at 20and 21 through which a pin may be passed.

The method oi? operation is as follows: Cheeses of yarn 15 are slid upona spindle 1 16 until the latter is filled, this operation beingconducted with regard to all the spindles of an apparatusof the typedescribed in the prior specification No. 1454312. On each spindle isthen placed the top plate 14. The cylindrical collar 7 is then screwedupon the central rod 5Figure 1,and the lever 9 fitted thereto by meansof its bifurcated end 10. The bell shaped pressure member 12 is thenfitted to the lever 9 by a pin 22 which passes through holes in the lugs13 of said member and through hole in the lever 9. This hole 20 .is sosituated that when the pressure member 12 is fitted to the lever thesaid pressure member will hang directly over a top plate 14 of a spindle16 as shown in Figure 1. Downward pressure being then applied to thehandle end of lever 9 the pressure member 12 forces the top plate 14downwards, thus compressing the yarn mass beneath it. The position ofthe hole 18 in the spindle has been predetermined so that Whensufiicient pressure has been applied to the top plate 14' to give thedesired degree of compressibility to the cheeses the upper end of theextension 17 thereof has just cleared the lower edge of the hole, andthe latter is visible to the operator through the; slot 19 into thepressure member. A pin 23 is then inserted through hole 18 to keep thetop plate 14 in position, and the pressing means can then be applied bymeans of lever 9 and pressure member 12 to the top plate 14 of anotherspindle- 16 in the apparatus. The lever can be moved angularly aroundthe rod 5 for this purpose, owing'to the screwed connection of said rodand the collar 7 which supports the said lever.

Obviously any number of holes.20, 21,

may be formed in the lever corresponding to the number of concentricrows of spindle 16 in the apparatus; and any number of holes 18 may beformed in each spindle 15. Where large batches of one kind of yarn areto be dealtwith the invention presents a conspicuous advantage; inasmuchas only one hole may be made available in each spindle for the insertionof a pin- 23; and it is therefore out of the power of a care-' lessoperator to give uneven pressure to the yarn mass on one spindle ascompared with another.

In order to give a support to all the I si lvindles of any apparatus,when they are led with cheeses compressed as described above, and whenthe apparatus is being handled in the course of dyeing or analo-' goustreatment of the yarns thereon, we may provide a circular plate 24Figure4-which is provided with orifices at the necessary points to allow thesaid plate to he slipped over the extension 17 .of'the top plate 14 onall the spindles and the central rod 5 to rest, and being secured inplace by a nut lightly screwed down thereupon with the interposed washeron the rod or spindle 12 which is threaded for the purpose.

We may alter the details given without departing from the spirit of theinvention. For instance, the pressure member 14 may be a plaincylindrical tube of the necessary dimensions having diametricallyopposite longitudinal slots in the upper end thereof, and the pin 22 oflever 9 be a permanent fixture in the said lever, one pin being fittedin each of the holes 20 and 21. The pressure i'nember, thus modified,being placed in position, the pin 22 on pressure bein applied to thelever 9 would fit in the slots in the pressure member, thus impartingthe necessary compression effect to the cheeses 15. i We claim v 1. Thecombination, with a spindlefor supporting cheeses of yarn, of aretaining plate slidable on the spindle, a sleeve slidable over oneend'o-f. the spindle and bearing on the said plate,.means for slidingthe sleeve so as to compress the yarn, and means for preventing thereturn movement of the said plate after the yarn has, been compressed.'2..The combination, witha' spindleprovided'with a cross hole andadapted to support cheeses of yarn, of a retaining plate slidable on thespindle, a sleeve slidable over one end of the spindle and having aslotted end which bears against the said plate,

means for sliding the sleeve longitudinally on the spindle, and a pinfor engaging with the hole in the spindle, said pin being insertedthrough the slotted end of the sleeve on. the other side of theretaining plate from the compressed yarn.

3. The combination,- with a. spindle for supporting cheeses of yarn, ofa retaining plate 'slidable on the spindle, aremovable sleeve slidableover one end of the spindle and adapted to bear on the said plate, astationary support provided with a revoluble member, a lever pivoted'tothe said member and to the said sleeve and adapted to slide the saidplate onthe spindle to compress the yarn, and means forpreventing thereturn movement of the said plate after the yarn has been compressed,the said lever being movable circumferentially. of the said support tocompress the yarn on other-similar spindles.

In testimony whereof we have hereunto set our hands.
